T a/ZZ whom i?? may concern:

Beit known that I, JOSEPH M. DnMnRArH, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain Improvements in Candy-Machines, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to improvements in ro machines for coating candieswith any suitable composition, said machine being designed moreparticularly for coating with chocolate, but being capable of use forother purposes.

x5 My improvements are fully described and illustrated in the followingspecification and the accompanying drawings, the novel features thereofbeing specified in the claims annexed to the said specitication.

2o In the accompanying drawings, representing a candy-coating machineembodying my improvements, Figure lis a front View. Fig. 2 is a sideView as seen from the left hand of Fig. l. Fig. 3 is a plan view. Fig. 4is a partial vertical section on the line 4 Li, Figs. l and 3, lookingtoward the right. Figs. 5 and 6 represent the mechanism for operatingthe cover. Fig. 7 represents the slotted plate detached. Figs. 8 and 9are partial representations of one of the trays. Fig. l0 is a plan viewof the cover and stripper. Fig. ll is a section of one of the stirrers.Fig. l2 represents a modified manner of introducing the trays. i

A represents the tank or receptacle for containing the chocolate orother coating material and in which the coating operation is performed.The receptacle is provided with a double bottom B, forming a steam-space4o into which steam` is admitted for the purpose of maintaining thecoating material at the proper temperature. The steam is admitted at twoor more points, as at da', Fig. 3, through suitable openings in thelower side of the receptacle, to secure the equable distribution oftheheat, the steam being discharged at a single opening, as at b. Thereceptacle is sustained at a proper height by suitable legs, and belowit is placed the main driving-shaft ;Q C,Which receives motion by thetight and loose pulleys D. W'hen the machine is in operation, the shaftO revolves continuously, suitable clutches Fand G being provided bywhich the operative parts of the machine are brought into action. 5 Themachine is arranged so as 'to be fed from both sides, the inclineddripping-pans J J extending outward from the receptacle on oppositesides, so that two operators standing in front of the dripping-pans J Jcan al- 6o ternately insert and remove the trays filled with thearticles to be coated. The standards I l, arising from the opposite endsof the receptacle, support the operating mechanism by which the articleson the tray K are coated by being immersed in the material in thereceptacle. When one of the operators has placed a iilled tray in themachine, he engages the clutch F by one of the handlevers E E', the camL is started to revolve,V 7o and this, through the connection M, thesegment N, and pinion O, imparts rotary motion to the shaft Q, which,through the Vgears and racks P P R R', causes the tray K to descend intothe receptacle and to rise out of it again, after which the tray isremoved with the coated articles thereon. This operation is thenrepeated with another filled tray by the attendant on the opposite sideof the machine. The cover e first descends onto the 8o tray and holdsthe articles thereon during the coating operation and is removedtherefrom just before the completion of Athe upward vmovement of thetray. Vhen the clutch F is engaged, it causes the worm S to revolve withthe shaft O, and this imparts Amotion to the worm-gear T on the shaft f,

which carries the cam L. As the cam L revolves the cover e firstdescends on the tray K, and the cover and tray then descend to- 9ogether into the receptacle and are raised again therefrom, the cover eagain separating itself from the tray. The trayand cover descend fromtheir own Weight, being raised by the cam L as it revolves. After havingcomplet-ed a revolution,during which the tray has been depressed intothe receptacle and raised up again, the clutch F is automaticallydisengaged, the roller h on the arm i, attached to the lever E, comingin contact With the roo edge of the cam.

In Figs. l and 2 the parts are shown in the position they occupy when atrest, with the clutch F disengaged and the tray and supporting mechanismraised, the cover e being also elevated above the tray. The shaftfrevolves in boxes g g, attached to the lower part of the standard I. Asuitable journalboX may be used to support the outer end of the shaft C.

U is a slide which carries at its lower end the roller d, which bearsagainst the edge of the cam L. The slide U is slotted to engage with theshaftf, and it may be also guided by a suitable arm attached to thejournalbox g. At its upper end the slideU is jointed to the connectionM, which is pivoted to the arm Z of the segment N, which vibrates on thestud V, inserted in the standard I.

The segmental gear N meshes with the pinion O on the shaft Q, whichcarries the gears P P', which mesh with the racks R R', so that as theslide U travels up and down in consequence of the rotation of the cam Lthe tray K also travels up and down.

In order to start the machine, the operator pushes the lever E inwardtoward the receptacle, as indicated by the full and dotted lines in Fig.2, which movement frees the roller h from the cam L by shifting itinside the cam, thus leaving the cam at liberty to revolve, and he thenengages the clutch F by shifting the lever E from right to left, asindicated in Fig. l, which by the link 'm and lever o, engages themovable member of the clutch F with the other member, which is connectedwith the worm S. Any suitable clutch may be used-that representedconsisting of two circular plates, one of which is provided with aseries of holes in which pins on the other engage.

As the shaft C usually makes aboutseventyfive revolutions a minute, notime is lost in the engagement of the clutch. The startinglever E ispivoted on a stud j, and a spring n, Fig. 2, is arranged on the studbetweenthe lever and the receptacle, so that the lever can be shiftedinward by sliding it on the stud to disengage the roller h from the edgeof the cam L. During a portion of the revolution of the cam the roller his held behind the cam; but as the cam revolves and its cutaway portioncomes opposite the roller h the spring n forces the roller h outwardover the edge of the cam, which by its continued rotation forces theroller h radially outward,

`the movable member of the clutch F. The

lever o is pivoted to an arm attached to one of the journal-boxes q,Fig. l, which depend from the receptacle for the purpose of. supportingthe driving-shaft C. The startinglever is arranged so that the machinemay be put in operation from either side. This may be done in anysuitable way; but in the construction shown I arrange a rock-shaft 0"across one end of the machine and provide it at one end with the leverE' and at the other end with an arm s, the point of which engages in aslot in the lever E, as indicated in Fig. 1. By this arrangement themachine may loe started from either side, the lever E' moving outwardfrom the tank when the lever E moves inward to disengage the roller hfrom the cam L, and both levers swinging together when the clutch F isengaged or thrown out.

At their lower ends the racks R R are provided with the cross-heads F'F", from the outer ends of which depend four posts c c' c" 0"', whichare provided with projecting pins or lugs which support the tray K atits corners, the arrangement being such that a tray may be readilyinserted between the posts or removed therefrom from either side of themachine. The mechanism forA causing the cover to descend on the traywill be understood from Figs. 4, 5, and 6. As soon as the shaft Q beginsto revolve the racks R R', the cross-heads F F", and the tray K begin todescend. It is necessary to make the cover e close down on the candieson the tray before the latter reaches the coating material. To do this,I attach to the cross-heads F' F" an arm d', which operates inconnection with a slotted plate g and a lever 7L' to accelerate themovement of the cover at the beginning of its descent, so that it willovertake the tray and travel farther downward with it. The lever h' ispivoted atj' to the upper end of the arm ol', and its free end isconnected by the link Z' to the stem m', attached to the cover e. Whenthe part-s are at rest with the cover e above the tray, the pin lt' onthe lever h' rests in the upper end of the curved portion of the slot'n' in the plate g'. When the cross-head F begins to descend, the pivoty" is moved downward, the lever h swings about the pin 7c' as a pivot,its free end moves downward, the link Z straightens out, and the cover eis forced downward and makes contact with the tray or the articlesthereon.

The operation will be readily understood from Figs. 5 and (3, in whichthe slotted plate g' (shown in Fig. 4) is omitted for the sake ofclearness of representation. l The rack R' slides in a guide S",attached to the standard I'. The slotted plate g' is supported at ashort distance inside the rack by the bent straps fi', attached to theguide S", the arm d', lever h', link l', and stem m' occupying the spacebetween the slotted plate g' and the guide S". The stem 'm' slidesthrough and is guided by an openingin a boss on the crosshead F". Thelower end of the stem m' is attached to the end frame or one of thecrossbars of the cover e. The pin 7c' travels in IIO the slot 'n' in theplate g'. It will be understood that at the end of the upward or returnmovement the cover e will be lifted off of the tray. It will also beunderstood that similar mechanism is used on the opposite end of thecover and tray for the purpose of securing the proper relativemovements.

Immediately above the cover is placed the heater T', which consists of asheet-metal case of suitable dimensions, inclosing a coil of pipe u",the ends of which q' q" project above the casing to receive thesupply-pipes. The heater is supported in any suitable way, such as bythe arms t t depending from the straps i'. The pipe u" is bent on itselfin any suitable way, so as to afford a sufficient supply of heat to thecover. In the construction shown it is soldered to the sheet metalforming the lower surface of the heater, and the arrangement is suchthat the cross-rods a', Fig. lO, of the cover come into actual contactwith the heater. By this arrangement the cover is maintained at such atemperature that it does not chill the coating material when in contacttherewith. To prevent loss of heat, I fill the heater T' above the coilu" with one or more layers of asbestos r', Fig. 4. It will, however, beunderstood that the principal function of the heater is to keep thecover warm, so that the coating material does not adhere to it and thatthis result may be accomplished in various different ways.

After the articles on the tray have been coated they should be allowedto drain over the inclined dripping-pans .I J', which return thedrippings to the tank. The draining is facilitated by jarring orshaking, and for this purpose the trays after coating are slid intoA thetray-'supports t, arranged at the proper level on each side of themachine. The traysupports are pivoted bars t, provided on their innerfaces with ledges or rows of pins d", Figs. l and 3, arranged at such adistance apart as to receive the tray between them. The bars t arepivoted at h' to asuitablehead c" on the upper ends of thesupporting-rods a. The bars t are provided with pins c', which preventmore than a half-rotation as the tray after draining is turned over,sothat a suitable board or other flat surface may be used to support thecoated articles after their removal from the tray.

The mechanism for jarring the trays while on the tray-supports, so thatthe articles may be properly drained, consists, essentially, of thecontinuously-revolvin g serrated wheel WV and devices for transmittingthe vibration produced by such wheel to the tray-supports. The serratedwheel W is driven from the pulley Y, Fig. 1, on theshaft C by the beltu', being supported by a movable frame fu, which swings on the shaft Cand is arranged to be raised upward to produce the jarring action by thetreadle X and connection w. Vihen the serrated wheel l/V is raisedupward, it is brought in contact with the lower end of the slidingspindle Fig. l, which at its upper end is attached to the horizontal bargy, from the ends of which the uprights e' reach upward alongside of thetable or dripping-pan J and at their upper ends carry the traysupportst, one at each end of the tray. The spindle reciprocates in a suitablesupport A', attached to the side of the tank, and it is provided withthe spiral springf', which increases the effect of the jarring movement.The springf' is coiled about the spindle so, and bears at its upper endagainst a shoulder in the interior of the support A' and at its lowerend on a collar g" on the spindle. The serrated wheel W is preferablyhardened and also the lower end of the spindle at, which is beveled tocorrespond with the inclined or ratchet teeth of the wheel, whichpreferably gives some twenty or thirty vibrations for each revolution.The spring f increases the effectiveness of the vibration, increasingthe rapidity of the descent of the tray. The movable frame t' isconstructed in any convenient way so as to swing about the shaft C as anaxis and to permit the wheel W to be elevated by the depression of thetreadle X, which is pivoted to a bracket on the floor and connected tothe frame by a link fw, as shown. When a filled tray has been coated andshifted into the tray-supports and the coated articles on it aredraining onto the inclined table or dripping-pan J,the operatordepresses the treadle, raises the Wheel W into contact with the lowerend of the spindle fr, and thus imparts to the traya vigorous jarringmovement, which materially hastens the drainage and quickly puts thecoated goods into condition to be removed from the machine. ThejarringImechanism is duplicated on the opposite side of the machine from thatshown in Fig. l. A serrated wheel W', Fig. 2, carried by a movable frameo', driven from the pulley V by the belt u'" and operated by the treadleX' and connection tu', is employed to impart a vibratory motion to thespindle and thus through the rod y and uprights z to the traysupports t.

Any suitable mechanism may be employed to keep the chocolate or othercoating material properly stirred. For this purpose I arrange in thereceptacle A the reciprocating stirrers Z Z', which are thrown intooperation by the hand-lever II, operating the clutch G on the shaft C.(See Fig. l.) At the opposite ends of the receptacle the stirrers Z Z'are arranged to swing inward across the lower part of the receptacle,being put in operation by the hand-lever II.

composition. At the other end of the tank is a corresponding stirrer Z',Fig. 3, the two being proportioned so as not to come in contact witheach other. The crank K' works the crank M' on the lower end of theshaft D', connected with the stirrer Z through the connection L',and thecrank M' through the connection N' and crank O' vibrates the stirrer Z'.The shafts of the stirrers reach downward through the bottom of thereceptacle and through suitable journals, preferably cast with the legs,as indicated in Fig. 4c. The stirrers preferably consist of two or moreradial bars having inclined surfaces with an open space between themadapted to thoroughly mix the coating material,as indicated in thesection, Fig. 11. The stirrers when folded, as indicated in Fig. 3, willnot interfere with the descent of the tray.

Any suitable tray may be employed adapted to the shape of the articlesto be coated. In Figs. 8 and 9 I have represented the tray K, which isadapted to candies of an ordinary shape and which consists of the frameV', the cross-wires W", the transverse wires s', which are bent downwardlaterally and again upward to form the contacts z' and to inclose acandy of an ordinary shape, as shown. Any other suitable tray adapted toany other form of candy may be employed.

The cover for the tray is represented in Fig. lO. It consists of theside bars Y with a series of parallel wires z" extending between them.It may be provided witha stripper U', which consists of a plateperforated to slide on the wires z" and provided with one or more rodsD", by which it is operated. The cover slides up and down on the posts cc' c" c'" and is provided with a cross-bar r", to which the stem m' isattached.

The tables or dripping-pans are made with a double bottom, as indicatedin Fig. 4, and provided with openings for the connection of suitablepipes. The connections may be so arranged as to permit the use of steamor hot or cold water underneath the receptacle and the tables ordripping-pans.

The cross-heads F F" may be made shorter than as represented in thedrawings, which will in a measure facilitate the introduction of thetrays by bringing the posts c c' nearer together. The lower ends of theposts may also be connected together by a bar N', Fig. l0, whichsustains the tray, instead of using the lugs t". (Shown in Fig. 8.) Apin Z" may also be inserted in the posts to hold the tray down and toprevent its being raised by the covers adhering to the coating material.

In a modication represented in Fig. l2 -the pins d" are omitted from theupper inner portions of the tray-supports t to facilitate theintroduction of the trays. In this case there are three posts c c' 0"",which depend from the cross-bars F' F" at each end of the trays, eachpost being provided at its lower end with a supporting-lug ",whichengages under the tray. K" represents the position of the tray whilebeing inserted, its advancing edge being placed upon the lugs't'" at thelower ends of the central posts c"', after which its outer part ispermitted to rest on the inner portion of the lower row of pins d", andit is then slid into proper position, as indicated at K.
